Hi All,<br /> BTree Insert requires a data-structure called BTStack to report the page splits that have happened
inthe leaf pages to non-leaf pages upwards. It basically goes back and updates those non-leaf pages. But this will
neverhappen in a search operation. You never need to climb upwards for a Select statement. Actually we can clearly see
thatin the _bt_first function, as soon as we complete calling _bt_search, we call _bt_freestack to free it. So
unnecessarilya BTStack structure is getting formed and deleted.<br /> Inside _bt_search function, if we just add
aif condition to check whether access is for BT_READ, then we can avoid the creation of stack and also remove the
_bt_freestack in the _bt_first function. I just implemented the change and tested it and i am not seeing any
performancedifference(as expected).<br /> <br /> Still i thought of reporting it, so that whoever is
workingon it, can incorporate this change also.<br /><br />Thanks,<br />Gokul.<br />
